YARUMAL, Colombia -- Tucked away on a steep street in this rough- hewn mountain town, an old woman found herself diapering her middle-age children. It is Alzheimer's disease, and at 82, Mrs. Cuartas, her gray raisin of a face grave, takes care of three of her afflicted children..……. Large families, and intermarriage, have accelerated the spread. Mrs. Cuartas's fourth debilitated child, in Medellín, Carlos Alberto Villegas, …. is now often fed by baby bottle, married a distant cousin…….. With Alzheimer's in both parents' families, Mr. Villegas's three children could face extraordinary risk. One, Natalia, 22, asks: ''How long have I got, till I'm 35? There's no way out.''

“Someone at 47 may have a young family who would be helping to care for their parent - a role reversal…they probably wouldn't be able to appreciate their children growing up/participate in day to day activities.” Ava Nepute “…little difference between caring for our elders regardless of their age…because they all have a part to play, and again I emphasize their role as morale foundations; the 'loss' of which will affect the family unit equally at 47 and 77.” Steven Tan “The strong genetic link in early onset Alzheimer's may also be difficult to come to terms with psychologically…this could potentially lead to other mental illness in these groups such as anxiety, depression and a potential suicide risk.” Grace O'Doherty “Knowing that you, the carer, may soon develop the disease as well must only add to your troubles and stresses.” Hannah Goodchild “If I were in the position of someone of this age caring for someone of a similar age, I would feel afraid of what would happen and of coping alone.“ Lizzie Casselden “To watch your loved ones suffer and decline with a disease that you have a high chance of also developing sounds terrifying.” Ruth Hillier “There can also be feeling of anger and grief as both the carer and patient may feel that their future has been taken away from them.” Daniel Pierce White

Textbook definition In acceleration of thinking, associations are still formed normally but at a grossly accelerated speed. The goal is not maintained for long and the intervention of new thoughts produces “flight of ideas”.
